Two new carbazole alkaloids from Murraya koenigii.
Two new carbazole alkaloids named murrayanine (1) and 8,8' '-biskoenigine (2) were isolated from Murraya koenigii. The structure elucidations for 1 and 2 were carried out on the basis of 1D and 2D NMR experiments. Compound 1 was a novel carbazole alkaloid with a rare phenylpropanyl substitution. Compound 2 was a symmetrical dimer of the carbazole alkaloid koenigine and showed antiosteoporotic a...
متن کاملCarbazole Alkaloids from Roots of Murraya Koenigii (Rutaceae)
The study on petroleum ether extract of the roots of Murraya koenigii (curry leaf) which involves extraction, separations by using various chromatographic methods and structural determination by spectroscopic techniques have afforded two compounds; 3-methylcarbazole and murrayafoline A. The structure of the compounds were also confirmed by comparison with the previous works. Abstrak. Kajian ter...

Murraya koenigii (L) Spreng, commonly known as curry leaf, is used in traditional and folk medicine for treatment of various ailments. Three carbazole alkaloids namely, mohanimbine, koenimbine & koenidine and a flavonoid, quercetin (+)-D-glucoside were isolated from dichloromethane and methanol extract by silica gel column chromatography and HPLC, respectively and their structures were elucidat...
متن کاملBiological activity of carbazole alkaloids and essential oil of Murraya koenigii against antibiotic resistant microbes and cancer cell lines.
A total of three carbazole alkaloids and essential oil from the leaves of Murraya koenigii (Rutaceae) were obtained and examined for their effects on the growth of five antibiotic resistant pathogenic bacteria and three tumor cell lines (MCF-7, P 388 and Hela). The structures of these carbazoles were elucidated based on spectroscopy data and compared with literature data, hence, were identified...
